My-invention relates to a new and improved constructionbf frame for agricultural imp'lements' and the like, being espe eially designed for use with a United States Number 1,249,067, dated Dec. 4, 191 7 grantedto meon application Serial No. 31,5156 filedqMay 29,1915 of which the present application-is a division. It is the object of myginvention to provide a form I andq arrangement of frame. parts such as to be capableof withstanding the heavy stresses to be brought to bear in use upon the framework, especially in an (implement or other ;,machine employing a two-part axle construction the parts of which are movable independently of each other. The preferred -ineans by which I; have accomplished my objectsareillustrated in the drawings and are hereinafter specifically described. That which Ibelieve tobe new and desire to cover by this application is set; forth in the claims.

member at each side of the machine is connected by means of diagonally-disposed brace-bars 1' ?18 I of the frame 10. A bearing bracket 19 is secured between the outer ends ofthe bracebars 1718 at each side of the machine, each of said bearing brackets being shaped to fit snugly about the end of the arch and be- By this arrangement of frame-parts, the frame as a whole is rendered exceedingly strong and rigid forces brought to bear upon it.

A tongue 20 is the frame 10 by means of a transverselyext'ending bar 21 which is connected by means of bolts 22'to the said frame member 10. diagonally-disposed brace-bars 23'% being employed'for holding the tongue rigid laterally relative to the framework. A seat 25 of any suitable type is mounted upon the bracket 11.

.A double mold-board lister plow-body 30 isicarried by the fran'le'work through the arm is mounted upon the squared outer end of the crank axle 32 at one side of the machine, being connected by means of a coiled spring 36 with an arm 37 mounted upon the frame memberlO nearits-forward end. The spring 36 tends to cause rotation of the crank axlc-32-in the direction for raising. the plow-body30. Upon the squared end of the crank axle 32 opposite to that upon which the arm 35 is mounted, there is fixedly mounted a lever 43 by which the said crank axle is adapted to be turned in its bearings The lever 43 is adapted to be adjusted to anv desired position relative to a segn'lcntal rack 4L4 mounted upon with the adjacent side bar the various stressing pivotally mounted upon the frame member 10, the lever being adjustably held in position by means of spring latch mechanism 15 of any suitable type. By a manipulation of the lever i3-and the consequent turning of the crank axle member 32 the plow-body 30 will be raised or lowered out of or into operative ground-em gaging position, as is desired, the spring 1-523 are 1ournaled serving to assist in the plow-raising operation.

Mounted upon the plow-beam 31 in rear of the plow-body 30 there is suitable seeding mechanism comprising a hopper 46 provided with seed dropping devices of any approved type, by which seeds are adapted to be dropped successively as desired into the furrow opened by the plow-body 30. The seed dropping devices are preferably operated through the medium of covering devices 49-430 which are revolubly mounted relative to thehopper 46. One or botlrof the disks 49-50 is connected by any suitable train of mechanism with the seed dropping devices whereby upon the rotation of the disks 4950 by their engagement with the ground the seed dropping mechanism is operated.

The machine as a whole is supported by wheels 5556 which are journaled upon the horizontal portions of crankaxles 5758, respectively. The said axle members 57-58 in the brackets 19 and the brackets 1314. Each of these brackets is provided with a bearing block 59 (see Fig.

3) which cooperates with the bracket for revolubly supporting the axle members.

The axle members 57-58 are provided at their inner ends with arms or levers 60 61, respectively. The arm or lever 61 of the axle member 58 is pivotally connected by means of a link 62 with an arm or lever' 63 which is rigidly mounted upon a rock-shaft 6.4. which is journaled adjacent to the central portion of the arch 15. The arm or lever 60 of the axle member 57 is pivotally connected by means of a link 65 to an arm or lever 66 also rigidly connected with the rock-shaft 64, in the construction shown the arm or lever 66 being formed integrally with the rock-shaft 64. The rock-shaft 64. is journaled upon the-framework by means of a sleeve 67 forming a partof the clip 16, and a' sleeve 68 forming a part of a segmental rack member 69 which is secured by means of the bolt 17 upon the arch member 15. An arm 69 also connects the rack member 69 with the frame member 10 for bracing the rack member securely in position. A lever 70 is rigidly connected to the upper or rear end of the arm 63, being adapted to be secured by means of springlatch mechanism 71 at any desired point along the segmental rack 69.

y the provision of a double'arch structure and the diagonally-extending bracee' relative to the frame member 10, I have provided a very strong neat frame suitable for use with a two-part axle the parts'of which are movable independently of each other. Very heavy stresses are brought to bear upon this frame upon the alternate raising and lowering of the supporting wheels relative to each other, but I have found in practice that the frame is capable of withstanding the stresses and of maintainingits normal shape under trying conditions of use.

\Vhat I claim as my invention and desire to secure by Letters Patent, is-

1. The combination of a frame member, atransverse arch connecting the side portions of said frame member, a second arch connected to said first-named arch and extending at the sides beyond said first-named arch, and diagonally-extending brace-bars connecting each end of said second arch with said first-named frame member.

2. The combination of a frame member, a transverse arch connecting the side portions of said frame member, a second arch connected to said first-named arch and ex- I tending at the sides beyond said first-named arch and beyond said frame member, axle members journaled on said second arch and on said first-named frame member at opposite sides of the machine, and braces connecting the ends of said second arch with said first-named frame member.

3. The combination of a frame member, an inverted U-shaped frame member having its ends secured to the sides of said firstnamed frame member, a third frame member extending transversely secured to said second-named frame member and having its outer end portions extending diagonally downward beyond said second-named frame member, and diagonally-extending brace bars connecting the ends of said third frame member with the side portions of said firstnamed frame member both in front and in rear of said third member.

4. In an agricultural implement, the combination of a frame member, an arch extending across a short distance above said frame member and having its end portions extending diagonally downward and out ward into position opposite the sides of said frame member, means for supporting said arch firmly in position above said frame member, and other means serving to tie togcther the end portions of said arch to prevent their spreading laterally relative to each other whereby 'a truss bracing effect is secured.

5. In an agricultural implement, the com bination of a frame member, an arch extending across a short distance above said frame member and having its end portions extending diagonally downward and outward into position opposite the sides of said 1 frame member, means for supporting said arch firmly in position above said frame member, and diagonally-extending bracebars connecting the end portions of said arch with said frame to prevent said end portions from spreading laterally relative to each other whereby a truss bracing effect is secured.

6. In an agricultural implement 'the combination of a frame member having oppoositely-disposed sides, an arch extending across a short distance above said firstnamed frame member and having its depending end portions' fixedly connected to the sides of said frame member, a second arch superposed upon said first-named arch and having its end portions extending diagonally downward and outward beyond said first-namedarch, and means serving independently of said second arch to tie to gether the outer end portions of said second arch whereby a truss bracing effect is secured.
